NASA Space Shuttle Columbia Disaster
Estimated impact: $13B (shuttle program costs); 7 lives
The Space Shuttle Columbia disintegrated during re-entry, killing all seven crew members. Foam debris had struck the orbiter's wing during launch, but NASA management dismissed requests for on-orbit inspection and classified the foam strike as an accepted risk based on prior missions where foam strikes had not caused catastrophic failure.
Decision context
Whether to request Department of Defense satellite imagery to inspect potential thermal protection system damage on Columbia's wing after foam was observed striking it during launch.

Lessons learned
- Normalizing deviance by accepting prior foam strikes as evidence of safety rather than increasing risk is a hallmark of groupthink in engineering organizations.
- Status quo bias in risk assessments means that known problems are reclassified as "accepted risks" rather than addressed.
- Anchoring to past mission success in the presence of unresolved anomalies creates an illusion of safety that masks accumulating risk.
